Job DescriptionOur mission We're making Africa the first cashless continent. In 2017, over half the population in Sub-Saharan Africa had no bank account. That's for good reason—the fees are too high, the closest branch can be miles away, and nobody takes cards. Without access to financial institutions, people are forced to keep their savings under the mattress. Small business owners rely on lenders who charge extortionate rates. Parents spend hours waiting in line to pay school fees in cash. We're solving this by building financial services that just work: no account fees, instantly available, and accepted everywhere. In places where electricity, water and roads don't always work, you can still send money with Wave. In 2017, we launched a mobile app in Senegal for cash deposit, withdrawal, and peer-to-peer and business payments. Now, we have millions of users across 9 countries and are growing fast. Our goal is to make Africa the first cashless continent and that's where you come in... How you'll help us achieve it Wave is now the largest financial institution in Senegal and Côte d'Ivoire, with millions of users, growing rapidly year-on-year. And, we're still in the early days of our product roadmap and potential impact on people's everyday lives. We're looking for an experienced security engineer who's independent, excited about getting things done, and ready to hit the ground running. You'll primarily be responsible for our application security, working with our product teams to work on new systems to enhance our security posture. Our customers trust us with their money, and you'll be at the forefront of making sure we retain that trust! This broadly scoped role will allow you to get your hands on many different types of security projects, from direct application security to helping our infrastructure team think about security for our databases. As we integrate AI-powered agents into our engineering and operations workflows, you'll help define and enforce the guardrails around how we use them safely. This includes securing agentic tooling against prompt injection, excessive permissions, and data exfiltration — and building the policies and technical controls to govern AI usage across the company. Some experience with common industry certifications like ISO-27001 and PCI-DSS would be beneficial, although you won't be expected to run or oversee audits.

We move as fast as possible. Speed matters. It lets us try things quickly, get feedback early, and course-correct while it's cheap. So we write small PRs. We aim for MVPs. We leave TODOs and file follow-ups. We don't over-perfect v1. That said, we're building a financial product. Some things—like money movement, correctness, or security—deserve more caution. We like boring technology. We favor tools that are reliable, well-understood, and easy to debug. This keeps us focused on solving meaningful problems instead of wrestling with unpredictable infrastructure. If a new technology helps us move faster, build safer, or solve a real need, we'll consider it. But we don't adopt tools just because they're new—we adopt them because they're right. Simplicity is a strategy. It lets us focus our energy where it matters most: serving our users. #LI-DH1 #LI-REMOTE Our team • We have a rapidly growing in-country team in Senegal, Côte d'Ivoire, Mali, Burkina Faso, The Gambia, Uganda, Niger, Sierra Leone, and Cameroon plus remote team members spread across the world., • We're deeply passionate about our mission of bringing radically affordable financial services to the people who need them most., • We foster autonomy for our employees.
